HINGE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed January 30, 1911. Serial No. 605,419.

To all whom it may concern:

Be it known that I, FREDERICK GRAAF, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Hinges, of which the following is a speciiication.

rIhis invention relates to an improvement in hinges, and has for its object to provide a hinge having a divided pintle, which acts as a wedge, whereby the hinge may be securely fastened at any angle with reference to its base or support. I accomplish this object by the mechanism illustrated in the accompanying drawing, in which- Figure l is a side elevation of a hinge, showing my improved pintle in position. Fig. 2 is a rear elevation of same. Fig. 3 is a section on the line A-B of Fig. l. Fig. 4 shows the hinge set obliquely with reference to its point of support. Fig. 5 shows the members of the pintle separated.

Similar characters of reference designate similar portions of the device, in each of the views.

In the drawing, l designates a member of the pintle, which consists of the base por tion 2 provided with the slot or oblong aperture 3. At right angles to the base is formed the shank 4, which may be of any convenient length, and to the end of which is formed a portion of a pintle having a rounded side 5, formed in a plane parallel with the plane of the base. This portion of the pintle is cylindrical in form at its point of union with the shank. But the outer' side 5a, is chamfered or cut away from that point to its extremity, so that it will form one half of a pintle, in the shape of a wedge. The other member of the pintle '6, has the corresponding portions similar to those above described, save that the outer side 7, of the pintle is rounded to conform to the side 5; while the opposite side 8, is chamfered to conform to the side 5a. It is apparent, therefore, that when the two chamfered surfaces are placed together, the two portions form a cylindrical body; and that by moving the Shanks toward each other, the transverse dimension of the combined members will become increased. These two portions are formed of such diameter, that when the eX- tremity of the member l is placed against the shank of member 6, their total diameter will be slightly greater than that of the aperture 9, of the hinge 10, in which they are adapted to operate. When the Shanks are separated slightly from that position, the hinge will swing freely thereon; but when they are forced together, the members of the pintle will bind in the hinge and hold it securely in place, at any angle which the service to be performed may require. By tightening screws in the eyes or slots 3 the members will retain their position, and the hinge will remain stationary wherever placed.

The particular use to which this hinge is to be applied is for hanging awnings. In hanging the hinges, which are at present in use, it is usually necessary to chisel away portions of molding or casing and more or less seriously deface the building, in order to place the hinge on a base parallel to the front of the awning, as it is only in this position that these hinges can operate.

Vith hinges formed after my improved plan it is obvious that the pintles may be secured upon the surface of any molding, or casing, as at 1l, in Fig. 4, without marring the structure in any way, and the hinge proper turned to and secured at any angle that the case may require.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In an awning hinge, the combination of a knuckle and a pintle comprising two members each having a base portion with a shank formed at right angles thereto, to the end of which is formed a half-spindle, the said half spindles being adapted to iit together to enter the knuckle of the hinge.

2. In an awning hinge, the combination of a knuckle and a pintle comprising two members, each having a base portion with a shank formed at right angles thereto, tothe end of which is formed a half-spindle, of wedge shape, said half-spindles being adapted to fit together to enter the knuckle of the hinge, whereby it may be locked at any angle with reference to the base.

3. In an awning hinge, a knuckle,-a pintle composed of two members, each having In testimony whereof I affix my signature 1n presence of tWo witnesses.

FREDERICK GRAAF.

a base portion provided with a longitudinal slot,-a shank formed at right angles thereto,-and a. halfspindle of Wedge shape formed at the extremity of each shank, each of Wedge shape and adapted to be adjusted upon the other, thereby binding each other in the knuckle.
